Abstract: Devices, systems, and methods for generating an emergency event spatial analysis are described herein. In some examples, one or more embodiments include a controller comprising a memory and a processor to execute instructions stored in the memory to receive a visual input from a first sensor and a spatial input from a second sensor, where the first sensor and the second sensor are located on an unmanned aerial vehicle (UAV), generate, based on the visual input and the spatial input, an emergency event spatial analysis, and display, via a user interface, the emergency event spatial analysis.

Abstract: Devices, methods, and systems for broadcasting a location of a fire are described herein. One device includes a controller configured to receive a report of a fire from a fire sensing device, determine a location of the fire based on the fire sensing device that reported the fire, and transmit a message including the location of the fire to a sounder device for broadcast by the sounder device.

Abstract: Methods for updating ephemeral keys on quick boot of a computing device, including determining, by a processor of the computing device, that a power-on transition is from a quick boot and generating, in a secure portion of the processor, a new ephemeral key for use in wrapping one or more encryption keys of a key ring for use in an unsecure portion of the processor in response to the quick boot. The secure portion of the processor may unwrap each of the one or more encryption keys of the key ring with a prior ephemeral key before wrapping the one or more encryption keys with the new ephemeral key.
